If your site shows a cPanel holding page straight after an SSL certificate has been installed, a cached DNS entry is almost certainly the cause.

## Why this happens

Installing an SSL certificate requires a small change to your domain's DNS settings. If you visited your site shortly before that change was made, your browser or computer may have saved the old DNS information locally. Until that cache expires - usually within a few hours - you will see the holding page instead of your site.

:::info
This only affects you and anyone else who happened to visit just before the change. New visitors will see your site without any problem.

## How to fix it

1. Clear your browser cache, then reload the page.
2. Flush your local DNS cache. On Windows, open a command prompt and run:

```bash
ipconfig /flushdns
```

On macOS, open Terminal and run:

```bash
sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
```

3. Try loading your site again.
